PROBLEM TO BE SOLVED: To provide a production method of an allyl compound of carrying out the dehydration allylation of a substrate having S, C or N which is a nucleophilic atom, especially S under the presence of a catalyst system consisting of a catalyst precursor having a specific structure and a specific ligand. SOLUTION: The production method of allyl compounds comprises as follow. A catalyst precursor chosen from Formula (1) and Formula (2) and a ligand are mixed, or a catalyst precursor, an allyl alcohol, and a ligand are mixed, then allyl alcohols and a substrate are blended and made to react. The ligand is quinaldic acid or picolinic acid, and the substrate is thiols, thiocarboxylic acids or the like. [Ru(C5H5)(CH3CN)3]PF6(1). [Ru[C5(CH3)5](CH3CN)3]PF6(2). COPYRIGHT: (C)2012,JPOandINPIT
An efficient and odorless synthesis of thioethers using 2-[Bis(alkylthio)methylene]-3-oxo-N-o-tolylbutanamides as thiol equivalents

Using 2-[bis(alkylthio)methylene]-3-oxo-N-o-tolylbutanamides 1 as odorless thiol equivalents, an efficient and odorless synthesis of thioethers has been developed. Promoted by NaOH in EtOH, the cleavage of 1 commences to generate thiolate anions, and the generated thiolate anions then react with halides to give various thioethers in good yield. It is noteworthy that only a very faint odor of thiols can be perceived during both the reaction and the workup. Using 2-[bis(alkylthio)methylene]-3-oxo-N-o-tolylbutanamides as odorless thiol equivalents, an efficient and odorless synthesis of thioethers has been developed. Promoted by NaOH in EtOH, the cleavage of 2-[bis(alkylthio)methylene] -3-oxo-N-o-tolylbutanamides commences to generate thiolate anions, and the generated thiolate anions then react with halides to give various thioethers in good yield.
